Help needed with internal parts of the horn & turn signal assembly (manette)

I was replacing the 4-wire harness for the horn and turn signal assembly on my 1955 Jaguar Mark 7 and one of the tiny bolts that the wires attach to fell back into the structure so I opened it further and of course some of the turn signal spring parts popped out. I think I can figure out where most of the little pieces go with the exception of these two little pieces at the bottom of the first photo. I have never been able to find any diagrams online of how all these parts go together. Anyone know where these 2 little pieces go? Or where I can send it for a rebuild?
